The hickey seen 'round the world

My son has a hickey. Thats right... and he gave it to himself. His fists are still in a tight ball most of the time. He has not quite figured out how to suck on his balled up hands, so his thumb pad, wrist and arm will have to do. He uses one hand to suck on and the other one to hold it up to his mouth. Kind of clever. One night he was going to town sucking on his arm. I just thought it was self soothing and he would stop once he started sucking to hard. Nope. We wake up the next day and Voila... a hickey.

 I wish I had a photo of the way he props his hand in his mouth. I will get one!
